Application'filed- December 23, 1926; Serial'No. 156,598.

This invention relates to improvements in registers and more particularly to a device designed primarily for registering the numher and' diameter of standing or un-cut trees on timber land. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings which form a part of this application and in which I i Fig; 1 is aplan view of the register.

On timber land it is usually desirable to know the exact number of standing trees, their kind and their diameters. The present invention provides means for ascertaining this information quickly and accurately with the minimum labor, the results. being conveniently registered and retained until copied" or other use made thereof as desired. The machine comprises a casing provided with an extensible scale or rack for measuring the tree diameters and one or more t'abulating units whereon the number of trees of a certain diameter is displayed. in units, tens or hundreds columns and also in a sum total at a point beyond saidcolumns.

Thereference numeral 1 denotes a hous- 5 ing integral with or supported by the spaced lateral bars 2, 3 which extend beyond said housing and areconnected by the hand grip or handle 4, the bar 2'being extended at one end beyond the housing to form the free shank 5. A partition 6 extendstransversely of the housing and divides it into two si1nilar compartments that extend from said partition to the bars 2, 3.

Extending longitudinally of the housing 1 and through the partition 6 with their ends arranged in the bars 2, 3 are the spaced parcross section on line "tition 6 are the gears 13 allel shafts T, 8, 9, 10 and 11. A similar shaft 12 lies mostly outside the housing but extends through the said partition 6 which is projected beyond the housing. Loose upon the shaft 8 upon each side of the parspaced equidistant one from the other and each of said gears being in mesh with a gear 14 loose upon the shaft 9. each gear 14 being fast to a disc 15 which is marked peripherally with the numerals from zero to nine and is loose upon said shaft.

Secured to one lateral face of each disc 15 upon the side remote from the gear 14 is a lug 16 that extends, at one end, beyond the disc peripherv for intermittent engagement with the teeth of a gear 17 loose upon the shaft 10 but fast'to one face of a disc 18, also loose upon shaft 10 said disc being numbered peripherally identically with the disc 15. A lug 19 fast to one face of each disc 18, remote from the gear 17 is adapted, as said gear rotates, for intermittent engagement with the teeth of a gear 20' fast to one face of a numbered disc 21, said disc and gear being loose upon the shaft 11. In corner extensions 22' of the housing 1 upon the shaft 12 thatcxtends through said extensions are the gears 23 fast to the numbered. discs 24; the discs 24 being known as the totals discs as they show the total number of trees counted by the units of the register. The shafts 9. '10, 11 and 12 are projected, at one end, beyond thehousing and provided with the caps 25 and thumb nuts 26.

Slidable longitudinally of the shaft 7 and keyed thereto in each unit of the housing s a counter gear27 adapted to register with any one of the gears 13 of the shaft 8 except the extreme outer gears of that shaft which will be denoted by character 13".

Each counter gear 27 is engaged by an elonto the bars 2 3 and extends longitudinally of the housing and through the partition 6 and has its ends imbedded in the bars2, 3, said rack being spaced slightly above the rack 31 to permit one side of the U-shaped yoke 28 to slide thei'ebeneath, the upper side of said yoke passing oversaid rack and said yoke sides being connected by the spacer spring 35 to yieldingly space them. A fork 36 has its prong end secured to the axle of the counter gear 27 and its shank passing across the upper side of the base of the yoke 28.

The fork 36 is connected by an expansion coil spring 37 to the housing while a pawl 38 passing I nects the fork 36 and the teeth of the counter trig gear 27.- VVit-hin the housing are the friction rollers 39 carried by the arms 40, said rollers bearing against certain of the numbered discs to yieldingly restrain their movement so that they will not move any through vibration or play from wear of the parts etc. t

An angular trigger 41 has its ends piyotally connected to the shaftT, each of said ers passing about posts 42, one such post bei-ng located adjacent each bar 2 and v 3 and one upon each side of the partition 6; each trigger passes over one fork 36 and its associated yoke 28'and is connected by links 43 that extend through perforations in the housing top to the finger bars 44 located outside the housing. One bar 44 may bear the word Cedar and one the word .Firif the device is used to compute dia neters and numbers of these trees. The cover 45 of the housing is formed with a plurality the housing and contents are manually moved over the rack 31 by means of the handle 4 the gear 48 rotates the pin shaft .and causes the pinion 49 traveling over the teeth of the, rack 29 toslowly move this rack, relative to the rack 31, in one or the other direction. a

Connected to one end of each trigger 41 ;by link 50 is a pawl 51 that registers with a toothed wheel 52, upon opposite ends of shaft 7, thatis in mesh with the gears 13 at the relatively remote ends of the shaft 8. When the machine is so adjusted that the distance between shanks 5 and 32 is eight een inches, as in Fig. 2, the counter gear 27 is in mesh with one gear 13. The space V between the said shanks 5- and 32 is the diameter in inches of certain trees. For

down through the yoke 28 con-.

hundreds "shaft 11.

revaeoe each treefound with a diameter of eight een inches one or the other spacer bar 44 is inanually depressed, depending upon whether the tree "is a cedar or fir, and this will cause the counter gear to advance, rotate one gear 13 for each tree of this diameter. Gears13 drive the units shaft and when ten trees have been registered by this gear 13 it, willhave made one completerevol'ution and the gear 14 in mesh with it on shaft 9, the units shaft, will have-made one complete revolution together with its numbered disc 15 and its lug 16 which will now have moved argear .17 of tens shaft 10 one-tenth revolution about its shaft. One hundred revolutions of the unit gear will "have caused ten revolutions of the gear 17 readable on its numbered disc 18 and this,

through the medium of lug 19 will have caused one revolution of a gear 20 on'tl e This total will have been registered by the'pawls 51 movable wit-h each trigger mpvement thus causing the wheels 52 torotate the train 13, 17, .20, 23. The gear 23 in each section of the housingdenotes the, total number of trees of any kind, cedar or fir, regardless of their diameters while the variousnumbered discs of the shafts 9, 10, 11 show, through the housing perforations 46 thenumber of trees of a given diameter.

' The teeth of the racks 29 and are of such relative distance apart and the gear 48 and pinion 49 of such relative size that OIIGlIlCll variation in the distance between the shanks 5,32 will cause a corresponding movementof the counter gear from one {to --an adjacent gear 13. if certain trees;

measuredare of such diameter tliat 'the relative adjustment of the shanks issu'ch as to throw the counter gear between two adjacent gears" 13, and not inmesh with jeitherya lightstroke upon a fingerfbar 44 will cause the yoke to engage with one of the high bevelled teeth 34 of the rack 33 and move the. counter gear and connections laterally intoposition to mesh with one or the other of said gears 13. The teeth34'arejstaggered relative to thegears 13 to permit them to function as described.

Any tree measurement is very easily and readily taken by simply applying the instrument to the tree trunk, one shank 5 upon onevside and the other shank 32 upon the opposite side. The distance between the shanks so spaces the operating andregistering mechanism described that manual de pression of either bar 44 will cause the numbered'discs to visibly register the diameters and number of all" trees measured and their totals. r

On the housing cover 45 two terminal rows of discs, one in each compartment, are denoted by the word Total and the remaining rows in each compartment are numbered.

The compartment intended for cedar trees has its transverse rows of numbered discs numbered from five to twenty. These figures denote inches. Trees five inches in di ameter, cedars, will be shown in row five; trees of seven inch diameter will appear, properly classified, in row seven, and the totals will appear in their rows] hen one job is completed and it is desired to set all discs at zero again the cover 45 is removed from the housing and the discs manually positioned.

In Figs. 5, 6 and 7 shown. The links 43 extend through a perforation in the housing and at their inner ends are fulcrumed upon a pin 53 and a rod 54 extending lengthwise ot the housing depresses forks 36; a return spring .55 for links 4-3 yieldingly retaining them in raised position. The forks are spaced from the yokes by springs 56 and the pawls 38 engage the counter gears from the top, or overhead, but the mechanism functions in the samemanner as in the form shown in the first four figures.
